We have just upgraded to the latest version of WordPress 4.4.2 and GovIntrant Version: 4.9.2. We have categories and tags on the right hand side of many pages. These worked to group things together, but after the upgrades tags no longer work, they don’t return any results. An example page can be found at http://socialsolihull.org.uk/healthandwellbeingnew/events/
Any help appreciated.

Working with Scott, we’ve done some digging and found that tags don’t work with news either, as well as events. But only when the tags are displayed the right hand side panel. They do work, however, when they’re appearing above the news item (as an example) once the news category has been chosen.

So, a bit more digging…

The non-working tags on the right have (as an example) a hyperlink to something like:

it works perfectly. We worked this out by looking at the working tags on the left. So, we still can’t get it to work but this might help.

We’ve also tested for the issue on other Govintranet installations we have and they display the issue as well – even those that aren’t WordPress networks. And we’ve tried resetting permalinks a couple of times…

We’ve installed it on test sites and the issue is sorted and tags work fine. For information, we’ve also tested it on a multi-site install and it solves it on that as well. see http://www.solgrid.org.uk.
